ly omgang@ the :sides nt such mn land are` preferably bolted thereto by the bolt 24 'In this manner the cross pieces are to one section of the slats.

` .securely held against displacement longitudinally of the car, but they can be easily removed by simply drawing the bolts and then lifting them until their fianges clear the brackets. I ,Y

The water from the melting v"ice as it passes down between the slats is caught by a pan orv series of pans 25. ln the construction illustrated, each of the pans covers onepan, moreover, extends beneath all of thev l slats of its section, the slats resting on it.

For purposes of convenience, we will hereafter designate this pan as the drip pan.

i '1, A second pan 27 is placed beneath each l drip-pan, but 1s spaced away therefrom to provide a space 28. This pan likewise has its sides and ends`29 upturned a distance .practically equal to that of the sides 26.

" aso The space 28 extends between the sides and ends of both pans, as well as between the bottoms oft-hem. For purposes of conveneience we will hereafter designate this pan as the condensation pan.

`A seriesY of perforations are provided in each pan, for permitting a free flow of air between'the ice and cooling chambers. lt is preferred, for reasons which will hereinafter be apparent, that the perforations in the drip and condensation pans should register, although this is not necessary.' The perforations in the drip pan are spaced in line with the spaces between' the consecutive slats, s'o that they will extend in rows lengthwise of the car.v A thimble 30 surrounds each perforation, extending above the bottom "25 of the drip pan anda sufficient distance to prevent leakage of the water from the melting ice throughv such i perforation, a hood 31 being secured to the top of each thimble, so that the Water cannot drlp Vdown directl into it, such hood being supported above tile upper edge of the thimble to provide a space 32 through which the air may circulate. A thimble 33 surrounds each of the holes in the condensation pan, and accomplishes a result similar to that of the thimbles on the drip pan. In order to secure thevmost peifect circulation of air, the perforations in the drip and condensation pans line up with each other, and the thimbles33 extend up a slight distance into the thinibles 30.l In this manner, a direct cireiilatin of ai-r may take place between the ice and cooling chambers, and with the least possiblenreslstance, but, "nevertheless,

a, certain portion 0f the (lOWniOWing CvOld By reason of the fact that the pans are made up from a number of sections, their abutting edges on the center lines 2v2 and 3-3 should be protected, so that water from the meltingice will not pass down through the space between the center slats and enter directly into the spaces between the two pans. For this purpose,a hood 34 is placed over the edges of the pans-on the centerI lines, as is well shown in Figs. l and 4. For the same reason, blocks 35 are extended out from the side and en dwalls ofthe car a suilicient distance to prevent ice from lying directly against such walls, and thus to prevent the water from entering directly between .the walls and pans at their outer edges.

In order to space the pans apart the desired distance, and to transmit the load from the slats to the crosswise extending chan nels, spacer blocks 36 are rovided between the pans. These are pre erably placed in rows directly beneath the slats, and boltsy 37 extend down through the slats, spacer blocks, and pans, to join all of these elements rigidly together. extend through these spacer blocks directly above the channels are passed also through the webs of the channels, so that the entire flooring, including the pans and slats, 1s

rigidly secured to the channels and held against longitudinal displacement in cases of sudden impact. Spacer blocks 39- are placed between, consecutive slats to retain them the desired distance apart, bolts 40 passing through `all of the slats and spacer blocks of a given section.

F rom the above construction it Will be seen that -each quarter of the flooring 4is practically a self-contained unit, and can beremovedy from thel car by simply removing the nuts Jfrom ,those bolts which extend throu h the channels, but without the necessit ot removing them from the other bolts'.

n thelconstruction illustrated in Fi s. 3,

4,' and 5, each slat is provided with a ,-bar

4l, so that the completed 'slatis T-shaped. I do not limit myseli` to any such construction, however, but l contemplate within the scope of my invention any desired shape of slat. For example, in big. 1 I havecut away the top portions of a number of slats and have laid 'a screening 4.2011 them, such The bolts 38 Whichico Lorelei Screening preventing pieces of ice from dropping down between the slats, but at the same time permitting a proper circulation of air and perfect drainage.

It was previously stated that the ends o the slats at the center of the car should preferably be raised higher than their ends at the ends of the car, so as to permit the water -to drain toward the ends. A drain pipe 43 is provided in each corner of the car, for carrying off the dripping water from each section of the flooring and pans.

I desire to call attention to the fact that by lining up the rows of pan perforations with the spaces between consecutive slats, the hoods or thimbles which protect such perforations may be extended up into the spaces between the slats, and thus the construction as a whole can be brought into a minimum of space, and can be made oi a more permanent character than would oth 'e1-wise be possible. Furthermore, in this manner the air movement is `considerably improved, because the circulation is directly to or from the perforations, with respect to the spaces between the slats. I desire also to call attention to the fact that, as far as l am aware, no other person has heretofore adapted a perforated drainage pan 'for use in connection with an overhead ice-bunker or chamber for car service. It will be seen that a peculiar relationship exis between such a pan and overhead ice chamber for car service, in that the ventilation of the cooling chamber is thereby greatly improved, and in that the cooling is much more eiliciently and perfectly accomplished than would otherwise be possible. This is because of the fact that tie water from the melting ice 'is caught in the pan, thereby cooling the same over its entire surface, and thus securing a maximum of cooling eil'ect in the chamber below, by reason of the direct contact of the air in such chamber with this large cooling surface. Nevertheless, a great amount of cooling is secured by convection, because of the currents of air which are constantly circulating through the perforations in the drainage pans between the ice and the cooling chambers.

I claim:

1. In a refrigerating car, the combination of a. substantially horizontally extending icc partition having a plurality of longitudinally extending openings lor the circula tion of air, a drip pan mounted beneath said partition for the collection of water from melting ice, there being rows of perforations in the said drip pan registering with the longitudinal openings ot the par tition, thimbles surrounding said perforations and extending upward into the longitudinal openings oi the partition, whereby the drip pan ma be mounted directly beneath the ice partition with its perforation thimhlee extending up into the openings of the same a condensation pan mount ed beneath the drip pan and provided with openings in registry with the openings of the drip pan, and thimbles surrounding the oaenings of the condensation pan and extent ing upwardly into the thimbles of the drip pan, whereby the condensation and drip pans may be mounted at a minimum distance from the ice partition, substan tially as described,

2. In a refrlgemtmg car, the combination of a substantially horizontally extending ice partition comprising a row of slats separated to provide longitudinal openings between them, a drip pan mounted beneath said partition for the collection of water ltrom melting ice, there being rows of pertoi-ations in the drip `pan in registry with the openings between the slats of the ice partition, thimbles surrounding said periorations and extending up into the openings between'the slats of the partition, a condensation pan mounted beneath the drip pan for the collection of water of condensation therefrom, there being perforations in the condensation pan in registry with the perorations of 4the drip pan, and thirnbles surrounding the perfor-ations of the con;
